Short Wave One More Step Toward Solving The Sleep & Alzheimer's Puzzle
Oct 29, 2020
NPR science correspondent Jon Hamilton, an expert on sleep's impact on health, joins the discussion on the surprising connection between sleep and Alzheimer's disease. He reveals new research showing how poor sleep may accelerate brain changes linked to Alzheimer's. The podcast delves into the glymphatic system's role in brain health, highlighting how deep sleep helps clear toxins like beta amyloid. Hamilton emphasizes the importance of sleep quality for cognitive health, presenting a compelling case for better sleep hygiene as a shield against cognitive decline.

Episode notes
Sleep and Alzheimer's Connection
- People with Alzheimer's often experience sleep problems.
- New research suggests poor sleep accelerates brain changes associated with Alzheimer's.
Mouse Brain Research
- Jon Hamilton visited Jeffrey Iliff's lab, which used lasers and microscopes to study mouse brains.
- Iliff's research focused on the glymphatic system, a brain-cleaning process during sleep.
Brain Waste and Beta-Amyloid
- Brain cells produce waste like carbon dioxide and ammonia, which the glymphatic system removes.
- Beta-amyloid, a waste product linked to Alzheimer's, builds up with insufficient sleep.
